/**
* Flush mode setting.
*
* When queries are executed within a transaction, if FlushModeType.AUTO is set on the Query object,
* or if the flush mode setting for the persistence context is AUTO (the default) and a flush mode
* setting has not been specified for the Query object, the persistence provider is responsible for
* ensuring that all updates to the state of all entities in the persistence context which could
* potentially affect the result of the query are visible to the processing of the query.
* The persistence provider implementation may achieve this by flushing those entities to the database
* or by some other means. If FlushModeType.COMMIT is set, the effect of updates made to entities in the
* persistence context upon queries is unspecified.
*
* If there is no transaction active, the persistence provider must not flush to the database.
